AB  - The Computational Fluid Dynamic (CFD) package COSMOS, was applied to simulate the flow through three versions of a centrifugal blood pump modeled with Solid Works. In this study, the 3 dimensional flow patterns through the artificial heart pump was predicted. The simulation was performed to detect Maximum Shear Force (N) through the pump, Averaged Static Pressure (Pa), Averaged Outlet Velocity (m s <SUP>1</SUP>), Pressure Drop (Pa) and Averaged Outlet Total Pressure (Pa). Three versions have been simulated model; the basic of Nikkiso blood pump with a circular outlet, the same pump modified with a rectangular outlet and a modified pump with a semi rectangular outlet. The pumps were simulated at T 37°C; with an impeller rotational speed of 3000 rpm clockwise, the cross sectional area of the outlet window was kept constant at 50 mm<SUP>2</SUP> for all versions and human blood was identified as working fluid with input/output volume flow rate of 6 L min <SUP>1</SUP>. The simulation results indicate that model (3) with a semi rectangular outlet has a better performance and gave the lowest average of static pressure and the lowest blood hemolytic levels with decrease of about 14.12% from the base pump model (1).
